Cell Energy and Cellular Transport Review

Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy, usually from the sun, into chemical energy in the form of glucose, using carbon dioxide and water.

The main products of photosynthesis are glucose and oxygen.

Cellular respiration is the process by which cells convert glucose and oxygen into energy (ATP), carbon dioxide, and water.

ATP (adenosine triphosphate) is the energy currency of the cell, providing energy for various cellular processes.

A concentration gradient is the difference in the concentration of a substance across a space, which drives the movement of substances from areas of high concentration to areas of low concentration.

In a hypotonic solution, the concentration of solute outside the cell is lower than inside, causing water to enter the cell, which may lead to cell swelling or bursting.

In a hypertonic solution, the concentration of solute outside the cell is higher than inside, causing water to leave the cell, which may lead to cell shrinkage.

An isotonic solution has equal concentrations of solute inside and outside the cell, resulting in no net movement of water.

The reactants of cellular respiration are glucose and oxygen.

Photosynthesis is crucial for the ecosystem as it produces oxygen and organic compounds that serve as food for other organisms.
